   * Changes
   * -------
   * 11-Aug-2003 : Version 1 (RA);
   * 18-Aug-2003 : Added tests for event notification when removing and updating
   *               series (RA);
   * 22-Sep-2003 : Changed to recognise that empty values are now null rather
   *               than zero (RA);
   * 16-Feb-2004 : Added some additional tests (DG);
   * 15-Jul-2004 : Switched getX() with getXValue() and getY() with
   *               getYValue() (DG);
   * 02-Feb-2007 : Removed author tags all over JFreeChart sources (DG);
   * 22-Apr-2008 : Added testPublicCloneable (DG);
